When most people think of rare species, they think of endangered ones that humans have caused to be rare through habitat loss, poaching, climate change and other disturbances. But some species have always been rare—occurring ...

The dangerous wobbling of pedestrian bridges could be reduced by using biomechanically inspired models of pedestrian response to bridge motion and a mathematical formula to estimate the critical crowd size at which bridge ...

Glulam timber bridges are viable and cost-effective options for replacing bridges on low-traffic county and township roads. That's what researchers at the J. Lohr Structures Lab concluded after testing a full-scale glulam ...
